hpplication 'November m,llllsflserlallici mmv This invention relates to cartridges (or lubricant or the like and more particularly to cartrid'g es or containers which are filled and sealed at the factory andfroni which the contentsiare adapted to be dispensed directly to'the point ol use.

U There are'anumber of advantages to themarketing of lubricants "in" factory filled, iactory sealed containers or cartridges, among which are easeand cleanliness of'h'andling, freedom from contamination, and insurarice to the consumer that he is receiving the desired gr'ade andbrand oi lubricant. It is essential, however, thatsuch cartridges be very inexpensive so "that they'will not increase too much the cost of the lubricantand that lubricant can'be dispensed from the car tridges quickly and easily and without leakage. It is, accordingly, one of the 'objectsof the present invention to provide a factoryilllediactory sealed lubricant cartridge -which is inexpensive to manufacture and irom which lubricant can be dispensed quickly and easily. Another object or theinvention'is'to provide a sealed cartridge for lubricant or the like which contains an annular packingfldisc'fto insure re- 4 moval of 'all of its contents without leakage. Still another object is to providea cartridge for lubricant in which one end of the cartridge is formed with a circular outwardly iacing shoulder to support an annular packing.

One cartridge embodying the invention is formed with a cylindrical sheet metal body having sheet metal ends crimped or otherwise permanently secured thereto. Adjacent-atleast 'one end, and preferably adjacent both ends, an annular packing disc of paper or'otherilbrous' materialgis placed 'in sealing engagement withthe "end and with its peripheryin sealing engage- 'ment withthe cartridge bodyq-If desired, the disc may be cemented to the cartridge end toinsure a tight seal therebetween and to prevent displacement of the disc.

One form of cartridge includes an'dnwardly pressed annular ring in its end forming anjoutwardly facing circularshoulder. This shoulder engages the radially inner edge of the annular packing disc to insure centering oi the disc and to provide a-further seal between the discand the cartridge end. In the illustrated iorms, the cartridges are adapted to contain'lubricant for" transmissions, differentials and the like and are intended'for use with devices for dispensing their contents under relatively low pressure.

Figure 4 illutrates one 'typepf dispenser with which anyoigthe above'described cartridges may be used but which has been shown with-the cartridge of Figure 2, The dispenser includes a framemember I] carrying a feed screw "at one end. A plate I9 is carried by the inner end ofthe feed screw I 8,,an'd=is adapted to [seat on the end H I2 of thecar-tridge. 'I he opposite end. of the frame I! carriesaidischarge nozzle 2I;having a rigid extension 22 extending toward the teed screw and of substantially the, same length as the cartridge. At its innerend the extension 22 rigidly carries a tubular; knife 231,.and a disc;24 formed .with an annular knifell of substantially the sameextern'ah diameter as ;;the internal. diameter of thecartridge. tTh-tdiscjl slidably v receivesla .1

series of rods "which are rigidly secured to a pusher plate 21, compression springs 2.surrounding the rods;2l and,urging-the plat'ei21 away from the disc 24.;

' In use acartridge is placed in the dispenser with the plate I9 engaging the end. and the pusher plate 21 engagingthe end I3; As the screw it is -turned;the.cartridge is: moved bodily toward the V discharge nozzle, forcing theplate 21 toward the plate and compressing the springs 28 until the' centralkniie 2i engagesthe endli andcuts out the centerportionthereoi as indicated at 29. 1

or 3 and has:v been -shown with i the cartridge of Figure 3, I Since the dispensers of Figures 4 and 5 are somewhat similar, parts in Figure 5 corresponding} to like parts in Figure 4 have beeniindicated by the sarnereterence numbers plus 100'. In this'dispenser the plate I I9 is formed with or car- 'rles the,annular-.-knife. I25 for cutting. out the cartridge end I Hand the pusher plate I21 is mounted on the pins I26 ,which are slidably carried by. the plate H9. Thepiate I24 is ri'gidlysecured tothe extension I22 andis formedwith guide flngers' IjII to receive and' center the cartridge" endU'The plate m also carries a fixed triangular knife m adapted topuncture the end of the cartridge.

In using this type 0!, dispenser; .a, cartridge, is placed .in position with one end lying within the guideflngers I30 and with the-pusher plate I21 engaging its other end. As the screw H3 is operatedthe'knife I23 will cut through the end of the "cartridge to form an outlet opening, the end orthe cartridge seating on the plate I24., Further j movementJoi'xthe screw II! will compress the springsI2l'until the kniie' I25 engages and cuts;

I'r desired 't'he pusher plate I21 may beitormed withiacentral openingjas shown at III sothatthe knife I22 will 'cut a hole in both ends of the cartridge when it is completely emptied, thereby destroying the cartridge.
